What the AI looks for in Aluminum Rods
- Machinability
- 2011-T3 is the free-machining choice; 6061-T6 machines well and welds; avoid soft 1100 or 3003 for turned parts. Soft alloys build up on the tool edge and leave poor finishes.
- Diameter tolerance
- Measure stock on arrival, and buy oversize stock if the finished part must hit an exact diameter. Budget rod is often slightly under or over nominal size.
- Straightness
- Prefer short lengths for small diameters. Thin rod bends in shipping and is hard to straighten without marking it.
Brands that matter
- uxcell: Small diameters in short lengths.
- Online Metal Supply: Larger diameters with stated alloys.
What to avoid
- Rod with no stated alloy for threaded or load-bearing parts.
